Postfix works as documented in regexp_table(5) and pcre_table(5),
i.e. each query stops at the first matching rule.
Postfix also works as documented in header_checks(5), i.e. DISCARD
causes Postfix to ignore the remainder of the message.

That would show the subjects that don't match patterns before /^Subject:/.

Unlikely. Linux, as many other systems, implements the POSIX regexp
API which is controlled by an international standardization group.
